Title: Improvements in and relating to fluid pressure braking apparatus
IPC: B60T13/66
Filed: 1919-05-26
Abstract: 148,669. Westinghouse Brake Co., and Rendell, A. W. May 26, 1919. Fluid-pressure. - In a combined straight-air and automatic fluid - pressure braking-apparatus, acceleration of the application and release of the brakes by straight air is obtained by means of electro-magnetic valve operated simultaneously with the ordinary straight air application and release. The main-reservoir pipe 1, automatic trainpipe 2 and straight-air control pipe 3 are as usual, the automatic train-pipe being connected through a triplevalve 4 on each vehicle to an auxiliary reservoir 6 and brake cylinder 5, and the straight-air pipe 3 being connected by branches 8, 9 to the exhaust port of the triple valve. The driver's brake-valve handle 11', when in the application position IV or release position II for ordinary straight-air actuation of the brakes, also closes circuits respectively energizing application or release magnets 14, 15, the former actuating to supply air from the mainreservoir pipe 1 by branch 13 to branch 9 of the straight-air pipe, and the latter actuating a valve to vent the straight-air pipe locally. In position VII of the driver's brake-valve handle, for effecting emergency automatic application of the brakes, a circuit is also closed which energizes an emergency valve magnet 21 to vent the automatic train-pipe locally to atmosphere. In this position of the driver's handle the magnet 14 is also energized, causing a straight-air application of the brakes should the triple valve fail to give the emergency automatic application.

Title: Treatment of cellulosic fibres
IPC: D06M13/348
Filed: 1943-08-14
Abstract: The water-receptivity, swellability, tensile strength, appearance and affinity for dyestuffs of cellulosic fibres, yarns and fabrics is improved by treating them separately, and in either order, with acrylonitrile and a solution of a strong hydroxide. The process is applicable to cellulosic fibres of all kinds, including regenerated cellulose and natural fibres such as cotton, jute, ramie and flax. Specified strong hydroxides which may be employed are sodium and potassium hydroxide and quaternary ammonium hydroxides, e.g. tetramethyl, tetraethyl, benzyltrimethyl, dibenzyl-dimethyl, tetraethanol and butyl-benzyl-dimethyl ammonium hydroxide.  The fibres are treated with acrylonitrile by soaking or dipping, preferably at room temperature, excess liquid is removed, the impregnated fibres soaked in a solution of the strong hydroxide, squeezed or hydro-extracted, washed with water or weak acid and finally dried. The temperature, concentration and time of treatment with the hydroxide solution may be varied according to the effect desired. The fibres may be treated under tension or otherwise.  In an example, it is stated that cotton sheeting treated according to the invention is dyed with Brilliant Blue 6BA to give a deeper shade than that obtained by dyeing the material treated with hydroxide solution alone.

IPC: B63C7/12
Abstract: 132,570. White, J. W., White, H., and Dorrian, J. Aug. 12, 1918. Sunken ships, raising.-The holes in the ship's sides are stopped by means of cover-plates held in position over the holes by electro-magnets. The electro-magnets may be attached to the vessel or to the cover-plates so that the plates become highly magnetic and hold themselves to the ship. The water is then pumped out of the ship. After the ship reaches the surface, the cover-plates may be bolted on in the ordinary way. To effect a better joint between the plate and the ship's side, a packing may be used. The packing may consist of iron filings in a suitable medium to form a cement which preferably hardens in water. The cover-plate may be a sheet of ordinary iron or steel. In the case of a large hole, one or more cross-beams may be temporarily held across the hole from the inside of the wreck. The magnetized plate then attaches itself to the beams as well as to the plating of the wreck around the hole.

Patent GB-133123-A (GB)
IPC: G05G15/04
Abstract: 133,123. Gunton, O. E., and Gilbert, W. Sept. 20, 1918. Band; periodic; actuated by driving-mechanism disengagers. - In clutch and brake gear for cutting out presses of the kind in which the machine is stopped at the end of one revolution, no matter what the position of the starting-treadle, the clutch and brake are separately operated for stopping by sliding members moving with the platen; auxiliary means lor preventing overrun due to mal-adjustment of the brake are provided. To start the machine, the clutch 40 is engaged and a brake band 27 is disengaged from a drum 26 on the machine shaft 21 by depressing the treadle 1 and thus rocking a shaft 3 which carries (1) an arm 57 connected by a rod 55 carrying adjustable nuts 56 to a trip lever 49, which is pivoted on a spring-controlled rod 43, adapted to actuate the clutch 40 through the lever 41, and bears on a cam surface 47 secured on a rod 46 reciprocating with the platen, and (2) a bell-crank lever 24 whose arm 23 is pivoted to a lever 25 connected to the brake band ends by a link 30, adjustable lever 29, and rod 69, the end 31 of the lever 25 normally resting on a lug 32 on a crosshead 33 reciprocating with the platen. Depression of the treadle first disengages the lever-end 31 from the lug 32, so that the lever falls and releases the brake, and the lever 49 is then disengaged from the cam 47 and the clutch is engaged. The treadle 1 is carried on arms 7 loose on the shaft 3 and provided with lugs on which is pivoted a trip lever 12 normally engaging an arm 9 fast on the shaft 3. The machine shaft 21 carries an eccentric 20 actuating a cam 18 loose on the shaft 3, which cam engages a roller on an arm 14 fast to the lever 12, so that, during the fall of the platen, the lever 12 and arm 9 are disengaged and the shaft 3 is returned to normal position by a spring 60, even if the treadle 1 is still depressed. This action brings the lever 49 into alinement with the rod 43, either by means of a spring 52 or by pcsitive action, and brings the lever-end 31 above the lowered lug 32. A cam 62 on the rod 46 keeps the clutch positively in action until the rise of the platen brings the cam 47 into contact with the lever 49 and disengages the clutch, the rise of the head 33 at the same time lifting the lever 25 and applying the brake. If the machine overruns the proper stop position, a pin 68 extending on both sides of the brake drum 26 engages members 66 pivoted to the parts 29, 30 and applies the brake in a positive manner; the members 66 are withdrawn during starting by an adjustable link 65 connected to the second arm 64 of the lever 24. To disengage the pin 68 and member 66, the machine must be reversed, thus affording an indication that the main braking mechanism requires adjustment. The arm 28 carrying the brake band 27 is carried on an adjustable eccentric pin 72.

Title: Improvements in ball-point pens
Inventor: KUDAR JANOS KALMAN
IPC: B43K7/02
Filed: 1951-06-06
Abstract: 712,409. Reservoir pens. MAREK, A. J. June 6, 1951, No. 13424/51. Class 146(3) In a ball-point pen the ink reservoir tube has one bore only throughout its entire length and has, in cross-section, at least one acute or obtuse-angled corner. In such a tube the capillary forces are greater than that of a cylindrical tube of the same length and volume. As shown in Fig. 7, the ink reservoir has the shape of an equivalent triangle in cross-section. To prevent undesirable ink-creep along the corners, the latter could be rounded, or the tube could be indented at 5 at regular intervals or constricted at regular intervals to provide grooves extending completely round the tube. The same purpose could be served by squeezing a plastic tube of circular cross-section into alternating triangular prismatic sections 7, 8, Fig. 11, which are rotationally displaced relatively to one another. Other crosssections, such as star-shaped, having four, five, or six radially-disposed triangularshaped, passages leading from a central circular section, could be used for the reservoir. The reservoir is open-ended, and a float member may rest on the central area of the ink meniscus to ensure stability and prevent leakage where a wide tube is used. This float may comprise an artificial "skin" in the shape of a hyperboloid, semi-ellipsoid &c. The passage of air bubbles into the duct that leads to the writing point is prevented by a baffle 16, Fig. 21, having a tapered end 17. As shown, the baffle is hexagonal in crosssection and forms triangular spaces 20 in the triangular cross-section reservoir 12. The tapered hexagonal end 17 enters a tapered circular bore 22 of the writing point 13, so that the ink space between the bore and the end 17 is divided into six narrow segmental-shaped ink passages which decrease in area towards the duct 15. Other forms of baffles which can used comprise ribbed plugs, or plain cylindrical plugs having conical ends. Specification 573,747 is referred to,

Title: Feature classifiaction in image analysis
IPC: G01N15/14
Filed: 1971-05-06
Abstract: 1395147 Image analysis IMAGE ANALYZING COMPUTERS Ltd 28 April 1972 [6 May 1971] 13591/71 Heading G1A [Also in in Division G4] In a system for classifying a region of a polished steel (white) surface containing oxide (black) and sulphide (grey) inclusions a video signal is detected against two reference levels as described in Specification 1390938 to provide two signals comprising constant amplitude pulses representing intercepts with oxide and sulphide inclusions respectively, the oxide inclusions being further classified by making two separate measurements on the first signal and comparing these two measurements to identify the kind of oxide inclusion. In Fig. 3 the two detected signals are applied at 10,56 respectively. The sulphide pulses at 56 are accumulated in a store 58 and read out to a counter 62 at the end of each field. The oxide pulses at 10 are accumulated in a store 12 and read out at the end of each field to one of three counters 14, 16, 18 according to the classification. A computer 29 such as is disclosed in Specification 1391056 accumulates values of the total horizontal and vertical projections of the inclusions; at the end of each field the two values are compared by dividing the horizontal by the vertical and comparing the quotient with a constant value K1; a signal X is generated if the quotient is greater than the constant (signifying long thin inclusions of type C) Fig. 2 (not shown). A simple anticoincidence computer 38 such as described in Specification 1264807 accumulates in a counter 40 the total number of inclusions. An agglomerater such as described in U.S. Specification 3795792 accumu lates in a counter 50 the number of closely spaced groups of inclusions. At the end of each field the number of groups is divided by the total number of inclusions and if the quotient is not greater than a second constant K2 a Y signal is issued (signifying a preponderance of goups of inclusions of type B) Fig. 2. According to whether the X or the Y signal is present the oxide pulses are read into counters 14, 16 respectively; if neither X or Y is present (signifying random inclusions of type D-Fig. 2) they are read into counter 18. Individual fields are classified by comparing the counts in accumulators 12, 58 and separate counts are made of the number of fields classified as predominately of each type A, B, C or D. The counters 14, 16, 18, 62 may accumulate pulses over say 500 small fields of a sample to arrive at a classification for the whole sample sheet. A number of alternative schemes for sub-classifying the oxide inclusions are mentioned in the Specification.

Title: Improvements in and relating to valves
IPC: F16K1/42
Filed: 1946-05-06
Abstract: 611,691. Valve accessories. BRITISH THOMSON HOUSTON CO., Ltd. May 6, 1946, No. 13693. Convention date, May 7, 1945. [Class 135] In a shut-off valve for high pressure fluids, the valve disc 11 is arranged in the inlet chamber 3 and is supported only by a valve stem 12, 14 slidably mounted in a bushing 17 secured in sealing engagement with the inner wall of the outlet chamber 5, the bushing 17, the valve seat 4, the valve disc 11 and an external aperture closed by a removable head member 9 being so proportioned that on removal of the head member 9, the bushing 17 may be withdrawn from the valve housing as a unit with the valve disc 11 and the valve stem 12, 14. The bushing 17 contains a ring 20 and two sleeves 18, 19, the wider diameter stem portion 14 moving with appreciable clearance 23 in the sleeves. When the valve is open, leakage through the clearance space 23 is prevented by a conical shoulder 21 on the stem engaging a correspondingly bevelled part 22 on the ring 20. Any leakage through the space 23 whilst the valve is moving is led away through ports 28 and other ports (not shown). The bushing 17 is held against a gasket 27 in a recess 40 by studs 24 and nuts 25 which also serve to secure a cover-plate 26. The valve is operated by a motor connected to the valve housing by a bracket 15 and studs 16. The valve seat member 4 is secured in the housing 1 by an annular weld 8 which allows for differential thermal expansion. A cylindrical shield 29 welded to the head member 9 and lying close to but not touching the valve disc 11 when the valve is open shields the valve disc from the dynamic forces due to the flowing fluid and so prevents flutter. The shield 29 is surrounded by a strainer comprising a perforated support cylinder 34 carrying a mesh screen 35.
